File sharing program designed for architects and builders

With this program an admin user sets up user accounts and assigns them to projects. When a user logs in they can upload/download and comment on files that are in projects they are assigned to. Everything a user does is logged, so that you KNOW if someone has reviewed that latest autocad revision. Whenever a file is uploaded to a project all users assigned to that project are emailed. The admin user can opt to have file access's emailed to them. If you like the demo, or are interested in an installation please give me a email.
